Personal amp evolution

Seeing the over night success of the speaker evolution thread, it may be interesting to see what type of amp(s) we have all run. Same deal as the other thread-we will sort of create a puzzle of our systems you'll have to visit multiple threads to put everything together!!! ;)
For me I started:
Adcom GFA-565 monoblocks
Rotel RB-990bx
Jeff Rowland Design Group Model 5
Balanced Audio Technology(BAT) VK-60

either a CAT JL2, BAT VK-75se or Tenor 75Wp on the horizon.
To many to name, but journey has ended with a Toolshed Transcendence 300b Amp. Absolutely gorgeous looking but even better sounding. Matt is a master builder.

I posted in Nov 2017 how I picked up the Ayre VX-5 Twenty but I sold it the following July, so it didn't really work for me.  I then picked up a Magnus Audio MA-400, which has worked well with my current setup.  I'm in the process of selling my speakers so I can move to bigger full range speakers and eliminate the JL sub, which was similar to a system I had 15 years ago.
This amp evolution has been years in the making. Unfortunately its been a lot of mistakes with a need to play around. As you get older playing around gets tiring and looses it thrill.
Here goes.
